Question Mouse and keyboard both light up but do not work ?

[my name is jeff]

I have the strangest problem.

Both my mouse and keyboards have stopped working on my desktop. My mouse lights up but does not register any input. My keyboard with two USB's lights up but does not register input either. My second keyboards LED's does not light up and does not register any input. This keyboard only has one USB input.

I accidentally spilt a couple of drops of water on my keyboard. I cleaned the PCB when I went to plug it in, the lights lit up, but it does not register any keyboard strokes. I tried to switch USB port's with my mouse now the mouse lights up and does not work. I tried connecting an older keyboard that one does not work either. I tested both keyboards and the mouse with my laptop they work fine.

• I recently updated some drivers on my desktop pc
• I reset the bios.
• The pc boots up normal even though there is no keyboard or mouse connected.
• I tried using the front USB's and the same thing happens.

Update your post to include full system hardware specs and OS information.

What drivers did you update, source?

Include PSU: make, model, wattage, age, condition?

Do the keyboard and mouse work on another known working computer?

Do other known working keyboard(s) and mouse (mice) work on your desktop?

Determine if the problem follows the keyboard and mouse or stays with the desktop.
